CASING FOR ENGINE-STARTER AND LIGHTING UNIT,

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed November 5, 1914. Serial No. 870,365.

To all wk om it may concern Be it known that I, FRANK E. FISHER, acitizen of the United States, residing at Detroit, county of lVayne,State of Michigan, have invented a certain new and useful Improvement inCasings for Engine-Starters and Lighting Units, and declare the follow--ing to be a full, clear, and exact description of the same, such as willenable others skilled in the art to which it pertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this specification.

My invention relates to an inclosing case for an electric motor andgenerator to adapt them for use as an engine starter and light ing unit.

One of the objects of the present invention is to construct an inclosingcase or shell aving an integral dividing wall forming separate chambersto respectively receive the armatures of the motor and generator inwhich the several pole pieces for the motor and generator are integralwith the walls of the case.

Another feature of the invention consists in dividing the case by avertical partition wall integral with the outer wall thereof to form achamber entirely independent of the chambers in which the armatures arehoused, to receive a train of gears and a clutch mechanism connectingthe armature shafts of the motor with the armature shaft of thegenerator in turn directly coupled to the crank shaft of the engine (notshown), the object of the partition wall separating the gear case fromthe armature chambers being to insure against the passage of lubricantinto the armature chambers from the gear case.

Other advantages and improvements will hereafter appear.

In the drawings accompanying this specificationz-Figure 1, is aperspective view of the case with the end covers removed. Fig.

2, is an end elevation of the case with the armature chambers removed.Fig. 3, is a longitudinal section on line 33 of Fig. 2. Fig. 4, is anelevation of the opposite end of the case showing the gear chamber,theend plate being removed.

Referring now to the letters of reference placed upon the drawings: A,denotes a chambered casting provided with a vertical plate covering theerator.

partition wall B, integral with the outer walls of the casting.

B, indicates a horizontal partition integral with the outer wall of thecasting and with the vertical partition forming a chamber C, for thearmature of the motor D, (indicated by dotted lines in Fig. 2,) with alike chamber E, for the armature of the generator D,also indicated bydotted lines in said figure.

C, C C, C", are pole pieces for the motor formed integral with the wallsof the casting. I

E, E E I are pole pieces for the generator, which are also integral withthe walls of the casting.

F, F, are openings in the partition wall B, through which the shafts ofthe armature of the motor and generator project into a gear chamberG;the openings being fitted with suitable gaskets f, f to prevent thepassage of lubricant from the gear chamber into the armature chambers ofthe casting.

G, denotes in dotted lines a train of gears housed in the chamber.

H, indicates a plate forming the end wall of the gear chamber providedwith a projecting annular flange H adapted to support a suitable bearing(not shown) for the armature shaft of the generator.

h, denotes a gasket encircling the shaft of the generator supported in arecess provided in the end plate H.

g is a gasket in the collar Gr part of the partition wall B,the ingadapted to support a suitable ball bearing (not shown) for the armatureshaft.

I, indicates a cover plate for the opposite end of the casting having anannular flange I, forming a chamber 1, for the commutator and brushes ofthe motor and gen- The cover plate is also provided with recessedportions J, J, in alinement with the respective armature shafts of themotor and generator, to receive the supporting bearings (not shown) forthe shafts.

Having indicated the several parts of the case by reference letters itsconstruction and manner of housing the respective parts of the motor andgenerator will be readily understood. By casting the pole piecesintegral with the walls of the case, I am enabled to materially reducethe cost of manufacture ;and by combining the motor and generator in asingle unit, the necessary labor the upper collar beand space requiredfor installation is reduced to the minimum.

Having thus described my invention what I claim is z- Y I 1. As a newarticle of manufacture, an inclosing case for an electric motor andgenerator com rising a chambered casting, an integral su stantlallyhorizontal wall dividing the casting into upper and lower chambers toreceive the armature of a motor an generator, pole pieces for the motorformed integral with the walls of the casting, pole ieces for thegenerator formed integral with the walls of the casting, an integralsubstantially vertical wall dividing the casting to form a gear chamberseparate from the aforesaid chambers and provided with openings forthepassage of the respective shafts of the motor and generator, a plateremovably closing the outer side of the gear chamber, said removableplate having an 1nwardly directed recessed bearing disposed in alinementwith the opening which establishes communication between the gearchamber andthe generator chamber. and a removable plate to cover theouter sides of both the aforesaid upper and lower chambers.

2. As a new article of manufacture, an inclosing case for an electricmotor and generator comprising a chambered casting, an

integral substantially horizontal wall dividing the casting into upperand lower chambers to receive the armatures of a motor and generator,pole pieces for the motor formed integral with the walls of the casting,pole pieces for the generator formed integral with the walls of thecasting, an integral substantially vertical wall dividing the casting toform a 'gear chamber separate from the aforesaid chambers and providedwith openings for the passage of the respective shafts of the motor andgenerator, a plate removably closing the outer side of the gear chamber,isaid removable 'plate having an inwardly directed recessed bearingdisposed in alinement with the opening which establishes communicationbetween the gear chamber and the generator chamber, and a removableplate to cover the outer sides of both the aforesaid upper and lowerchambers, said latter removable plate having outwardly projecting upperand lower recessed portions forming bearings disposed opposite the motorand generator chambers, respectively.

In testimony whereof, I sign this specification in the presence of twowitnesses.
